Littleton, Colorado (PR Newswire – September 2, 2011) Ur-Energy Inc. (TSX:URE, NYSE Amex:URG) The U.S. Bureau of Land Management (BLM) has conveyed to Ur-Energy (or the “Company”) its schedule for the completion of an Environmental Impact Statement (EIS) for the Lost Creek Project in order to satisfy its obligations under the National Environmental Policy Act. The BLM also indicated that it anticipates completion of the Record of Decision for the Lost Creek Plan of Operations early in the summer of 2012. In order to meet this time frame, the BLM is incorporating by reference portions of the analysis prepared in the Nuclear Regulatory Commission’s SEIS, and tiering off of that analysis where applicable.

The anticipated timing of the BLM approval complements the Company’s existing sales agreement and expectation to deliver significant uranium production into the market in 2013. With the receipt of a detailed and well thought-out work plan from the BLM, the Company is preparing to break ground on the Lost Creek ISR facilities in mid-summer 2012. Construction will last approximately six to nine months and will be followed immediately by production from the first mine unit.

“We are pleased to learn that the BLM has set a firm time frame for the completion of its review” states Wayne Heili, President and CEO. “The level of analysis and detail of the work plan gives us confidence that the BLM will complete its review on this schedule. Like the NRC which issued its license for Lost Creek last month, I anticipate that the BLM will determine that the Lost Creek Project will be allowed to move forward.”

Littleton, Colorado (Marketwire – August 29, 2011) Ur-Energy Inc. (TSX:URE, NYSE Amex:URG) (“Ur-Energy” or the “Company”) is pleased to announce that the Wyoming Department of Environmental Quality (“WDEQ”) has reclassified a portion of the production aquifer within the Lost Creek permit area as Class V (Mineral Commercial). The U.S. Environmental Protection Agency (“EPA”), in a letter dated August 23, 2011, formally agreed with WDEQ’s reclassification and in turn has issued an aquifer exemption pursuant to the requirements in 40 CFR §146.4. Both the WDEQ aquifer reclassification and the EPA aquifer exemption are required before injection into the uranium recovery wellfields can begin. The aquifer reclassification and exemption area includes all of the commercially producible uranium mineralization currently known and included within the Nuclear Regulatory Commission License area (see August 17, 2011 release for more information). This area encompasses all of the currently planned wellfields and will therefore not require changes in the foreseeable future.

EPA’s issuance of the aquifer exemption, in agreement with the WDEQ’s reclassification, means the only remaining WDEQ action required is the final approval and issuance of the Permit to Mine. Mr. Steve Hatten, VP of Operations, stated, “We are very pleased that the WDEQ and EPA have accepted the scientific methodology presented by Lost Creek for defining the aquifer exemption. This method will allow for the in situ recovery of uranium while protecting surrounding aquifers and ensuring compliance with the Safe Drinking Water Act.”
